Three key points for the purchase of high quality hardware locks

Home decoration, high-quality hardware locks are related to furniture safety, and you should see three points when purchasing.

First look at the lock implementation standards

Foreign countries have very strict standards for hardware locks, so the quality of imported products is relatively high. We can feel the quality of the locks. Generally speaking, the heavy lock has a relatively high quality; the lock body can not be pointed, and the tip is easy to injure, especially the lock handle end, the lock tongue and the lock body are three positions; the lock spring is good. Flexible opening, high sensitivity and long service life. There are also many styles of locks, so be sure to keep in mind the style of the interior doors.

Second, look at the lock material

The lock material on the market is basically divided into stainless steel, copper and zinc alloy. High-strength stainless steel, strong corrosion resistance, no discoloration, is the best lock material; copper is more versatile, mechanical properties are superior, and the price is higher; the lock high-quality zinc alloy is strong and wear-resistant, corrosion-resistant, and easy to form. Mostly used for mid-range locks.

Look at the surface treatment of the lock again (home improvement supervision)

The surface treatment is roughly divided into electroplating, spraying and coloring. The locks form a dense protective film on the surface of the product through surface treatment, which acts as anti-corrosion and anti-rust, making the lock more beautiful and durable. The dense protective film is also a standard for measuring the quality of locks. The locks of good quality are mostly plated, the coating is fine and smooth, even and moderate, the color is bright, and there are no signs of bubbles, rust and oxidation.  

Silicon Metal

Metal silicon, also known as crystalline silicon or industrial silicon, is primarily used as an additive for non-ferrous alloys. Metal silicon is produced from quartz and coke smelted in an electric furnace. The content of main component silicon is about 98% (In recent years, 99.99% of Si is contained in metallic silicon), and the remaining impurities are iron and aluminum. , calcium and so on.
